I have the latest PSOC Creator, and I just checked cypress update manager. Im running windows 10 pro. Every time I make a change to top design, API is regenerated for each component. Only problem is, I have maybe over 30 components, and during the "Cleanup..." process, each component takes around 1 SECOND.

If I remember correctly, even down to PSOC Creator 2.2, the build process chugged along faster than this. I only noticed this on 4.1. Even my biggest projects didnt take 30 seconds to build before. Now a simple one can take around 50, and its specifically slowed down by this "Cleanup..." Process. The console line shows this for each component.

In my case it took like 15 minutes to build and compile. I just simple deactivate the antivirus real time analysis program(in my case McAfee). Surprisingly when i build and compile again just take like 2 minutes.
